FREDERICK LINDLEY HUNT SIMS, OF TORONTO, ONTARIO, CANADA.

AGITA'IOR FOR CARBID-GAS GENERATORS.

Specification of Letters Patent.

Patented May 4-, 1909.

Application filed July 17, 1908. Serial No. 44.4,097.

To all whom it may concern:

Be it known that I, FREDERICK LiNDLnY IIUNT Sins, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Agitators for Carbid- Gas Generators, of which the following is the specification.

My invention relates to improvements in agitators for carbid gas generators, and the object of the invention is to devise a cheaply constructed agitator readily adapted for various diameters of tanks.

A further object is to so construct the agitator that it will clear and remove the sludge, which adheres to both the bottom and wall of the tank.

A still further object is to so connect the operating rod to the agitator and protect the tank from the movement thereof, that there will be no liability of a hole being made in the tank.

To effect these objects I have constructed my agitator of a central casting securely bolted to the bottom of the tank and having a central pin forming part thereof, and a sweeping rod supporting spider preferably made of malleable iron and mounted on the pin and casting aforesaid and provided with longitudinally recessed bracket arms to receive the sweeping rods, which are bent up at the end parallel to the wall of the tank, an operating rod journaled in the bearing brackets secured to the wall and having an end loop through which one of the sweeping rods extend, such operating rod being provided with a suitable crank handle at the top, the parts being otherwise arranged and constructed in detail as hereinafter more particularly explained.

Figure 1 is a sectional perspective view of an agitator constructed in accordance with my invention. Fig. 2 is an enlarged perspective detail of the sweeping rod supporting spider, such spider being partially broken away and in section to eXlllblt the manner of connecting the sweeping rods thereto.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the tank. B is a central casting, which is securely bolted to the bottom of the tank by bolts B. I is a central pin secured in or forming part of the central casting. The top of the casting Bis flat to form a bear ing surface for the sweeping rod support C, which has a central orifice O through which the pin 13 extends. The support 0 is held from vertical displacement by a cotter pin D. The support O is provided with a series of longitudinally recessed bracket arms C" and into these arms extend the sweeping rods E. The inner end, which has a right angular bend, extends through the arm and is suitably riveted or upset to hold the inner end in place. The inner end of the rod E is also held to the arm by the bent lugs G which straddle the rod being hammered down over the rod from the straight position, which is the position in which they are formed when the casting is made. By this simple means the sweeping rods are normally held in place. The outer ends of the rods E are bent upwardly at it into a vertical position parallel to the wall of the tank and in proximity thereto.

The tank of the machine is, as indicated, cylindrical and my agitator it will be readily seen can be adapted to various sizes of tanks as the rods E need not be bent until it is de termined into what size of a tank the agitator is to be placed.

F is the operating rod, which is journalcd in suitable bearing brackets F riveted to the wall of the tank and is provided with a loopshape end F through which one oi the sweeping rods E extends. I provide a crank han dle F at the top ol the operating rod F and a projecting plate G beneath the bottom of the rod F and suitably secured to the bottom of the tank. The plate G prevents any liability of the rod F, when being operated, from wearing a hole in the bottom ol the tank. vi hen manipulating the rod F the agitator may be given an oscillating movement, so as to clear the tank ol sludge or agitate it to such an extent that the sludge may be readily drawn oil through a suitable i'aucct. The vertical portions E of the sweeping rods serve to clear the wall, so that there is no liability oi the sludge adhering thereto, which is an important desideratum where tanks are made with vertically moving lioats.

What I claim as my invention is:

1. In an agitator l'or carbid gas genera tors, the combination with a central casting suitably secured to the bottom of the tank and having a central pin and a horizontal surface surrounding the same, of a sweeping rod support journaled on the central pin, sweeping rods suitably secured thereto and an operat ing rod vertically disposed and held in suit able journal brackets secured to the wall 01 the tank and provided with a looped end through which one of the sweeping rods eX- tend as and for the purpose specified.

2. In an agitator l'or carbid gas generators, the combination with a central casting suitably secured to the bottom of the tank and having a central pin and a horizontal surface surroundingthe same, of a sweeping rod support journaled on the central; pin sweeping rods suitably secured thereto and an operate ing rod vertically disposed and held in suit? able journal brackets secured to the wall of the tank and provided with a looped end through which one of the sweeping rods ex: tend and a plate secured to the bottom of the tank underneath the bottom of the operatingrcd secured as and for the purpose specified.

3. An agitator comprising a' sweeping rod 3 7 support having a'central orifice by which it is I journaled on 1 pin in the center 01' the tank and provided with longitudinally recessed Gillating the same as and for the purpose bracket arms. and rods provided with down= 1 wardly bent inner ends extending through a E corresponding orifice in the arms and riveted I therein, and bent lugs at the outer ends ol' j the arms extending over the rods as and for 1 the purpose specified 4. An agitator comprising a sweeping rod 1 support having a central orifice by which it is journaled on a pin in the center oi the tank and provided with longitudinally recessed the arms extending over the rods, the outer ends of the rods being vertically disposed as and [or the purpose specified.

5. An agitator comprising a swee' ing rod support having a central orifice by w iich it is journaled on a pin in the center of the tank and provided with longitudinally recessed bracket arms and rods provided with dew-n wardly bent inner ends extending through a corresponding orifice in the arms and riveted therein, and bent lugs at the outer ends oi the arms extending over the rod and means connected to one oi the sweeping rods for cs specified.
